Anonymous Blizzard sources speaking to Kotaku suggest that Titan was a sci-fi MMO set on a near-future version of Earth. Players would join one of three factions warring for control over territories that included Europe, South America, the United States, and Australia. Blizzard planned to add new areas via post-launch expansions.

Players would hold down a job such as butchering, engineering, or entrepreneurship when not battling opposing factions. In addition to running businesses or shops, players could even start families - Blizzard reportedly hired a number of devs who had formerly worked on The Sims to help implement the AI needed to support a family system.

Like Blizzard's popular fantasy MMO World of Warcraft, players would be able to choose from classes, each with their own special combat abilities. For examples, Rangers were snipers with the ability to cloak, while Jumpers were quick and agile scouts with the ability to teleport.

Titan reportedly had a bit of a Team Fortress 2 style aesthetic to it, and player perspectives would switch between first- and third-person depending on whether they were currently in battle or just hanging out in a city.

Although Titan was never technically announced, Blizzard co-founder and CEO Mike Morhaime yesterday revealed that the project was cancelled because "We didn't find the fun. We didn't find the passion. We talked about how we put it through a reevaluation period, and actually, what we reevaluated is whether that's the game we really wanted to be making. The answer is no."

Titan sounds like it was an incredibly ambitious project, and perhaps that's why it didn't come together as well as hoped. What do you think - is Titan something you would've like to play? Was Blizzard right to cancel the long-in-development MMO? Let us know what you think in the comments.
